Description
FIELD OF THE INVENTION
[0001] Embodiments of the present invention generally relate to
buckle assemblies, and more particularly, to durable buckle
assemblies that are easy to operate. Embodiments of the present
invention may be particularly suited for buckle assemblies used in
military applications, but can find use in other suitable
applications.
BACKGROUND OF THE INVENTION
[0002] Traditionally, the military has used certain buckle
assemblies that may not be ideal for particular situations. For
example, the buckles may be attached to large items that are
airdropped during a particular operation. Typical plastic buckles
are susceptible to smashing upon impact. Moreover, other types of
buckles are susceptible to prematurely opening.
[0003] Thus, a need exists for a robust, durable and
easy-to-operate buckle assembly. That is, while a need exists for a
buckle assembly that is strong, durable, and reliable, a user
should be able to open and close the buckle assembly with relative
ease.
SUMMARY OF THE INVENTION
[0004] Certain embodiments of the present invention provide a
buckle assembly including a latch, a buckle frame, and a
spring-biased lever that maintains a connection between the latch
and the buckle frame. The latch may include a first mating member,
such as a retaining opening or window, and a first strap-engaging
member configured to receive and retain a first strap end. The
buckle frame may include a base integrally formed with sidewalls
configured to protect the latch in a secured position in which the
latch is secured to the buckle frame, and a second strap-engaging
member configured to receive and retain a second strap end.
[0005] The lever may be rotatably secured to the buckle frame. The
lever is spring-biased into the secured position. The lever may be
rotated into an unlatched position in which the latch disengages
from the buckle frame.
[0006] The lever may include a second mating member, such as a
protrusion or opening, configured to mate with the first mating
member in order to secure the latch to the buckle frame in the
secured position. The lever may also include a pin housing
integrally formed with an actuation handle, a spring-biased pin
operatively associated with the pin housing, and surfaces or
protrusions configured to abut a portion of the latch when a force
is exerted into the lever. The abutment of the surfaces into the
portion of the latch provides an additional retention feature that
prevents the latch from inadvertently dislodging from the buckle
frame.
[0007] Other features and advantages of the invention will become
apparent to those skilled in the art upon review of the following
detailed description, claims and drawings in which like numerals
are used to designate like features.

items and equivalents thereof.
DETAILED DESCRIPTION OF THE INVENTION
[0020] FIG. 1 illustrates an isometric view of a buckle frame 10
according to an embodiment of the present invention. The buckle
frame 10 includes a base 12 integrally formed with sidewalls 14.
Latch-covering ledges 16 are integrally formed with the sidewalls
14 at a latch-receiving end 18 of the buckle frame 10. The buckle
frame 10 is configured to securably mate with a latch (not shown in
FIG. 1) through the latch-receiving end 18.
[0021] Pin-retaining openings or channels 20 are formed through the
sidewalls 14 proximate a mid-section 22 of the buckle frame 10. The
pin-retaining channels 20 are configured to cooperatively receive
and rotatably retain a spring-biased pin (not shown in FIG. 1)
operatively connected to a lever (not shown in FIG. 1).
[0022] Web channels 24 are formed through the base 12 proximate a
web-retaining end 26 of the buckle frame 10. The web channels 24
are configured to receive and retain a web or strap (not
shown).
[0023] FIG. 2 illustrates an isometric view of a latch 28 according
to an embodiment of the present invention. The latch 28 includes a
frame-mating beam 30 integrally formed with a web-retaining panel
32. As shown in FIG. 2, the web-retaining panel 32 may be wider
than the frame-mating beam 30, thereby forming frame-abutting edges
34. When fully mated with the buckle frame 10 (shown in FIG. 1),
the frame-abutting edges 34 may abut against edges of the sidewalls
14 (shown in FIG. 1) of the buckle frame 10. The abutting
relationship between the frame-abutting edges 34 and the edges of
the sidewalls 14 acts to prevent the latch 28 from being
over-inserted into the buckle frame 10.
[0024] The frame-mating beam 30 includes a lever-retaining window
36 that is configured to receive and latchably retain a lobe or
other such protuberance (not shown in FIG. 2) of a lever (not shown
in FIG. 2). The web-retaining panel 32 includes web channels 38
that are configured to receive and retain a web or strap (not
shown).
[0025] FIG. 3 illustrates an isometric view of a lever 40 according
to an embodiment of the present invention. The lever 40 includes a
tube or housing 42 integrally formed with an actuation tab 44. A
channel 46 is formed through the tube 42 and is configured to
receive and retain a spring-biased pin (not shown) that secures the
lever 40 between the sidewalls 14 (shown in FIG. 1) of the buckle
frame 10 (shown in FIG. 1) through the pin-retaining channels 20
(shown in FIG. 1).
[0026] A lobe 48 or other such protuberance is distally located
from the actuation tab 44 and extends outwardly from the tube 42.
The lobe 48 is configured to be latchably retained within the
lever-retaining window 36 (shown in FIG. 2) of the latch 28 (shown
in FIG. 2).
[0027] A hole 50 or slot may be formed through the actuation tab
44. A string or webbing or other suitable device (not shown) may be
secured within the hole 50. The string may be pulled to rotate the
lever 40 into an unlatched position.
[0028] FIG. 4 illustrates an isometric view of a buckle assembly 52
according to an embodiment of the present invention. The buckle
assembly 52 includes the lever 40 retained between the sidewalls 14
through an internal spring-biased member (not shown) retained by
the pin retention channels 20. In the latched position, the lobe 48
(shown in FIG. 3) is retained within the lever-retaining window 36
(shown in FIG. 2) of the latch 28. The lever 40 may be caused to
rotate around a pin (not shown in FIG. 4) or rotate with the pin
upon movement of the lever. The spring-biased member within the
lever 40 ensures that the lever 40 remains secured to the latch 28
until such time as the spring force is overcome to allow the
separation of the assembly.
[0029] In order to unlatch the buckle assembly 52, the actuation
tab 44 (see FIG. 3) is urged in the direction of arrow A either by
a user directly engaging the actuation tab 44, or by a user pulling
on a string secured to the actuation tab 44 through, for example,
hole 50 (see FIG. 3). That is, the lever 40 is rotated against the
force exerted by the spring force provided within the lever 40. As
the actuation tab 44 rotates in the direction of arrow A, the lobe
48 is dislodged from the lever-retaining window 36. Thus, the latch
28 may be removed from the buckle frame 10.
[0030] When the actuation tab 44 is disengaged, the force exerted
by the spring within the lever 40 returns the lever 40 to the
position shown in FIG. 4. The latch 28 may then be mated into the
latch-retaining end 18 of the buckle frame 10 in the direction of
arrow B. As the latch 28 encounters the lever 40, the frame-mating
beam 30 (see FIG. 2) moves into the lobe 48 (shown in FIG. 3) and
moves the lever 40 in the direction of arrow A. During this
movement, the lobe 48 slides over the top surface of the
frame-mating beam 30 until it encounters the lever-retaining window
36 (shown in FIG. 2). The lobe 48 then moves into the
lever-retaining window 36, which securely retains the lobe 48
therein.
[0031] The sidewalls 14 protect against unintended engagement. That
is, the sidewalls 14 provide a barrier that prevents unintentional
lateral forces engaging the lever 40 or the latch 28. Further,
sidewalls 14 and the ledges 16 prevent the latch 28 and lever 40
from being damaged while the latch 28 is secured within the buckle
frame 10.
[0032] The buckle frame 10, the latch 28, and the lever 40 may be
formed of metal, in order to provide strength over plastic
alternatives. For example, the buckle assembly 52 may be formed of
carbon steel, die cast steel and/or aluminum. Additionally, the
buckle frame assembly 52 may be easily moved between latched and
unlatched positions through the lever 40.
[0033] FIG. 5 illustrates an isometric view of a latch 54 according
to an embodiment of the present invention. The latch 54 includes a
frame-mating beam 56 rotatably connected to a strap-adjustment base
58. The frame-mating beam 56 includes a lobe-retaining window 59
formed proximate a mating end 60 and a rolled beam 62 rotatably
secured around a crossbar 64 of the strap-adjustment base 58. The
strap-adjustment base 58 may be formed of molded plastic or other
suitable material. The latch 54 may be used with the buckle
assembly 52 (shown in FIG. 4) instead of the latch 28.
[0034] FIG. 6 illustrates an isometric view of a latch 66 according
to an embodiment of the present invention. The latch 66 includes a
frame-mating beam 68 rotatably connected to a strap-adjustment
member 70. The strap-adjustment member 70 may be a stamped piece of
metal. The latch 66 may be used with the buckle assembly 52 (shown
in FIG. 4) instead of the latch 28.
[0035] FIG. 7 illustrates an isometric view of a lever 72 according
to an embodiment of the present invention. The lever 72 includes a
pin housing 74 integrally formed with an actuation handle 76. The
pin housing 74 includes a pin passage 78 configured to receive and
retain a pin (not shown). A lobe 80, or other such protuberance,
outwardly extends from the pin housing 74. The actuation handle 76
includes an arch-shaped engagement cavity 82 that is configured to
allow a user to engage the actuation handle 76 with a finger or
thumb.
[0036] The lobe 80 is configured to be latchably retained by a
lever-retaining window of a latch. Additionally, the pin housing 74
includes flat latch interface surfaces 84 on either side of the
lobe 80. The latch interface surfaces 84 are configured to abut
against surfaces of a frame-mating beam (such as the frame-mating
beam 30 shown in FIG. 2) positioned on either side of a
lever-retaining window (such as the lever-retaining window 36 shown
in FIG. 2). When the lever 72 is initially engaged to unlatch a
latch from a buckle frame, the latch interface surfaces 84 are
compressed into the frame-mating beam, thereby providing an
additional retention feature that prevents the latch from
inadvertently dislodging from the buckle frame. The force exerted
by the latch interface surfaces 84 increases as an unlatching force
increases. However, the lever 72 is configured so that an
unlatching force exerted by a user overcomes the compressive force
exerted by the latch interface surfaces 84 into the frame-mating
beam in order to desirably unlatch the latch from the lever 72.
[0037] FIG. 8 illustrates an isometric exploded view of a buckle
frame 86 and the lever 72 according to an embodiment of the present
invention. In order to assemble the lever 72 to the buckle frame
86, a portion of the spring 98 is preferably first placed within
pin passage 78. Thereafter, the lever 72 and spring 98 are
positioned over the base 88, and between the sidewalls 90 of the
buckle frame 86 so that the pin passage 78 is aligned with the
pin-retaining channels 92. A pin 94 is then passed through an
opening 99 in the spring, a pin-retaining channel 92, into the pin
housing 74 of the lever 72 through the pin passage 78, and out the
other pin-retaining channel 92.
[0038] The spring 98 may be a coiled spring having an elongated
loop 100. The elongated loop 100 includes an end that is configured
to hook around the sidewall 90 of the buckle frame 86. The spring
98 includes another end that is strategically placed within lever
72. The spring 98 is configured to move about or with the pin 94.
The spring 98 is further configured and adapted to engage both the
lever 72 and frame 86 to thereby bias the lever 72 in relation to
the frame 86. The spring 98 and the pin 94 cooperate to form a
biasing member that spring biases the lever 72.
[0039] FIG. 9 illustrates an isometric exploded view of a biasing
member 102 according to an embodiment of the present invention. The
biasing member 102 includes a pin 104 (that can be slotted) and a
spring 106. The spring 106 includes a straightened end 108 that is
configured to abut against, or within, a base of a buckle
frame.
[0040] FIG. 10 illustrates an internal cut-away view of the lever
72 secured within a buckle frame 110 according to an embodiment of
the present invention. The spring 106 and pin 104 are shown within
the lever 72. As shown in FIG. 10, the straightened end 108 of the
spring 106 is retained within a notch or cavity 112 formed between
the base 114 and a sidewall 116 of the buckle frame 110. The notch
112 covers the straightened end 108 or tail of the spring 106,
thereby removing the end 108 from the area of latch travel. Thus,
the notch 112 acts to prevent damage to the spring 106 and the
latch (not shown in FIG. 10) by ensuring that the latch does not
undesirably engage the spring 106.
[0041] Additionally, free rotation of the spring 106 is prevented
due to the straightened end 108 of the spring 106 being securely
retained within the notch 112. That is, the notch 112 acts to
anchor the straightened end 108 in place. Thus, the biasing member
102 exerts a constant closing force into the lever 72.
[0042] FIG. 11 illustrates an isometric view of a buckle assembly
120 according to an embodiment of the present invention. The buckle
assembly 120 includes a latch member 122 that is retained within a
buckle frame 124 by a lever 126, similar to the embodiments
discussed above. The lever 126 is secured to the buckle frame 124
by a pin 130 and spring. As shown in FIG. 11, a straightened end
128 or tail of the spring securely hooks around, or to, an outer
surface of a sidewall 132 of the buckle frame 124. Thus, the
straightened end 128 is not within the travel path of the latch
member 122 within the buckle frame 124. The other end of the spring
is positioned within the lever 126 to operatively provide the
desired spring force to the lever 126 in relation to the frame
124.
[0043] As mentioned above, the components of the buckle assemblies
may be formed of various metals, plastics, and other such
materials. Additionally, a hinged cover may be positioned over a
portion of the lever to prevent accidental engagement of the lever.
Further, while the lever is shown as a separate and distinct
component, the lever may alternatively be integrally formed with
the buckle frame. Additionally, while the latch is shown and
described having a lever-retaining window, and the lever includes a
protrusion that is retained within the window, the latch may
include the protrusion while the lever may include a window or
cavity that retains the protrusion.
[0044] Thus, as discussed above, and shown in the figures,
embodiments of the present invention provide a robust, durable and
easy-to-operate buckle assembly.
[0045] Variations and modifications of the foregoing are within the
scope of the present invention. It is understood that the invention
disclosed and defined herein extends to all alternative
combinations of two or more of the individual features mentioned or
evident from the text and/or drawings. All of these different
combinations constitute various alternative aspects of the present
invention. The embodiments described herein explain the best modes
known for practicing the invention and will enable others skilled
in the art to utilize the invention. The claims are to be construed
to include alternative embodiments to the extent permitted by the
prior art.
